The Shrine of Hazrat Ali, also known as the Blue Mosque, is a mosque in Mazari Sharif, Afghanistan. It is one of the reputed burial places of Ali. It is the building which gives the city in which it is located, Mazari Sharif (meaning "Tomb of the Exalted") its name.
According to Shi'a Muslim belief, Ali was originally buried by his two sons, Hasan and Husayn in an undisclosed location, which was later made known by the great, grandson of Husayn and Sixth Shi'a Imam, Ja'far as-Sadiq - as the grave that is found within Imam Ali Mosque in Najaf, Iraq.
